CARLING-SOCKET FOR CAR-FRAMES.

SPECIFICATION forming part of Letters Patent No. 470,744, dated March15, 1892.

Application filed July 31, 1891.

To all whom it may concern.-

Be it known that I, WALTER E. OOFFIN, a resident of Marshall, in thecounty of Harrison and State of Texas, have invented certain new anduseful Improvements in Carling- Sockets; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

The invention relates to carlings for the roofs of cars, such as usedfor transporting live or dead freight.

Heretofore the side plates of cars have been weakened by mortiscs, andthe carlings have also been weakened by the forming of tenons or tenonsand lips on their ends. These tenons and lips have been liable to wearin the mortises and also to break, split, warp, or turn. Further, acarling of the usual kind cannot be removed or replaced withoutspreading the car-frame and disturbing the roof.

The invention has for its object to provide means for strengthening thecar and securing the carlings in place in such manner as to avoid theuse of tenons and mortises and to provide for the removal or insertionof carlings when desired.

In the accompanying-drawings, Figure 1 is single carling and a tie-rodshown in section. Figs. 3, 4, and 5 are respectively rear, front, andside elevations; and Fig. 6 is a vertical section of a holder adapted toreceive the end of a carling.

Reference-letter 1) denotes the roof-boards.

(t denotes a carling; c, a plate; (I, a post; 6, the car-siding; f, aface-plate, and g molding.

it indicates a tie-rod extending from side to side of the car andthrough the plates, as represented.

2 indicates a holder for the carling end. It is made of metal andprovided with holes 70 for bolts or screws, whereby it can be securelyfastened to the plates 0.

Z denotes holes for the tie rods. These holes are located near andpartly in the side walls of the pockets, whereby all tendency of thecarlings under the great and various Serial No. 401,284. (No model.)

strains to which they may be subjected to be pulled out of the pocketsis efiectually obviated.

. The carling-holder has a pocket, preferably of rectangular shape andinclosed by the walls 5 5 m,as represented. The holes for the variousbolts are formed in flanges, which latter are' extended outwardlysufficient at n to provide that the holes shall not all be in onestraight line. The holes for the tie-rods may be formed '60 partially inthe walls m. Four fastening-bolts for each holder and two tie-rods maybe used; but these numbers may be varied. As indicated, the tie-rodspass through the carlingholder, the main side plate, the siding, and theface-plate on each side of the car, and are secured by nuts on theirends. Before they are put in position each end of the carlings isinserted in the pocket of a holder, which holders are then fastened tothe plates, as stated.

To remove a carling or to replace one, it is only necessary to releasethe rods and the fastenings of the holders, whereupon the operation canbe effected without disturbing the root or spreading the car-frame.

Each end of the carlingis preferably of the full size or nearly of thefull size of the adjacent part thereof and closely fits the pocket,whereby its full strength is preserved and lia- 8o bility to split,break, wear, or twist is avoided. Should, however, a carlin g be widerthan usual it can be fitted by reducing its end somewhat, as indicatedat o'in Fig. 1.

The constant and various strains to which 8 5 carroofs and frames aresubjected in addition to their liability to many extraordinary injuries,renders it especially desirable 'that they be made as strong aspracticable and that the construction be favorable to repairs, go andthese desirable objects are attained by the present improvement, which,however, is not confined to the exact form, size, and proportionsindicated, as these may be varied, provided substantially the samemechanical 5 principles and construction are employed.

I am aware that the use of holders with pockets adapted to receive theends of braces or beams is not new, and I do not broadly claim suchdevices.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, it is declaredthat what is claimed is 1. In a car, the upper side plates, incombination with a carling and with carling sockets or holders securedto the said plates, the upper side of each holder being in the sameplane as the upper face of its plate on which the roof-boards rest andeach provided with a pocket to receive the end of a carling, and atie-bolt passing through openings in the holder and through the plateand provided with a nut on its outer end, substantially as set forth.

2. A holder for the end of a carling having a pocket and provided withflanges having holes for fastening screws or bolts and having separateholes for the tie-rods located close to and in contact with the walls ofthe pocket, whereby the rods are held near the carlings, substantiallyas set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.
